RADIATOR.

Specification of Letters Patent.

Patented July 4, 1916.

Application filed January 14. 1914. Serial No. 812,058.

To all whom it 121 (13 concern:

Be it known that I, Earn. k. S'rmnorr- 1531', a citizen of the United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Radiators, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to radiators or.

water'cooling devices for automobiles and to an arrangement thereof which combines simplicity of construction with great effectiveness because of the position of the cooling elements and the few seams or joints required.

The invention consists the matters hereinafter set forth and more particularly pointed out in the appended claim.

In the drawings, Figure 1 is a view in end elevation, partially broken away of a radiator that embodies features of the in-' vention; Fig. 2 is a view in detail in vertical section through a portion of,thecooling section; Fig. 3 is a view in transverse section through a portion'of the cooling section; and Fig. 4 is a view in detailof a spacing plate. I I I Referring to the drawing a frame 1 of suitable design and material has an upper water space 2 or supply tank and a lower water space or tank indicated at 3, these parts being in communication through upright water spaces formed by a cooling sec tion whose general conformation 'is indicated diagrammatically at 4. The latter which is of the honeycomb type is formed of plates arranged in pairs and extending from the upper member 2 to the lower member 3. One of the plates 6 of each pair is corrugated transversely, the corrugations being angular and preferably sharply defined. The companion plate 7 is likewise corrugated and is also provided with spacing ribs 8 that extend from the outer convex part or crest of each corrugation to the ad joining plate 6 of a companion pair, the spacing ribs resting in the concave angles of said plate 6. The spacing ribs are formed by folding the plate upon itself so that l lateral off-sets are obtained. These may be completely closed-or may be slightly opened if desired. The plates. of each pair are held in spaced relation so as to form sinuous water passages by the margins.9 and 10 thereof which are slightly inset toward each other and when completed are sweat soldered or intimately connected together to form a close joint.

One result of the construction isthe fewness of joints as there are no-seams to be closed save along the lateral margins of the plates and at the insertion thereof of the plates into the upper and 'lower watcr spaces. The spacing ribs are an integral part of one of the plates and therefore there is no leakage possible in any connection between the ribs and theplate. Because of the sinuous paths traversed by the water the area exposed to the cooling'eflcct o the 7 .air 1s considerable greater than if the passages were straight from top to. bottom.

Obviously, .changes in the details of construction may be-made without departing from the spirit of n y invention and I (lu not care to limit n iyself to any particular form or arrangement of, part What I claimis In a radiator, a honcycomb cooling section comprising pairs of spaced plates-having off-set margins permanently secured together; one of said plates being corrugated. a rib formed at the crest of each corrugation. the other of said plates being continuousl corrugated and free of ribs with the projecting ribs received in the depressions thereof and the crests of the corrugations being directed toward and spaced ffoni the depressions in the first-named plate, the ribs of each pair of plates being arranged in alincmcnt and all pointing in the same direction and presenting cells having parallel end walls and angular side walls.

In testimony whereof I aflix my signa ture in presence of two witnesses.
